We have reported previously that there appears to be an intriguing sex-related functional asymmetry of the prefrontal cortices, especially the ventromedial sector, in regard to social conduct, emotional processing, and decision-making, whereby the right-sided sector is important in men but not women and the left-sided sector is important in women but not men. The amygdala is another structure that has been widely implicated in emotion processing and social decision-making, and the question arises as to whether the amygdala, in a manner akin to what has been observed for the prefrontal cortex, might have sex-related functional asymmetry in regard to social and emotional functions. A preliminary test of this question was carried out in the current study, where we used a case-matched lesion approach and contrasted a pair of men cases and a pair of women cases, where in each pair one patient had left amygdala damage and the other had right amygdala damage. We investigated the domains of social conduct, emotional processing and personality, and decision-making. The results provide support for the notion that there is sex-related functional asymmetry of the amygdala in regard to these functions - in the male pair, the patient with right-sided amygdala damage was impaired in these functions, and the patient with left-sided amygdala damage was not, whereas in the female pair, the opposite pattern obtained, with the left-sided woman being impaired and the right-sided woman being unimpaired. These data provide preliminary support for the notion that sex-related functional asymmetry of the amygdala may entail functions such as social conduct, emotional processing, and decision-making, a finding that in turn could reflect (as either a cause or effect) differences in the manner in which men and women apprehend, process, and execute emotion-related information.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 February 2026.
All research outputs
#10,949,072
of 32,106,825 outputs
Outputs from Neurocase
#255
of 603 outputs
Outputs of similar age
#60,903
of 163,457 outputs
Outputs of similar age from Neurocase
#3
of 4 outputs
Altmetric has tracked 32,106,825 research outputs across all sources so far. This one has received more attention than most of these and is in the 65th percentile.
So far Altmetric has tracked 603 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.8. This one has gotten more attention than average, scoring higher than 57% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 163,457 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one.
